以下は、変更ログからのニュースです。

Functionality added or changed:

* SHOW CHARACTER SET and INFORMATION_SCHEMA now properly report the Latin1 character set as cp1252. (Bug #11216 (http://bugs.mysql.com/11216))
* MySQL Cluster: A new -p option is available for use with the ndb_mgmd client. When called with this option, ndb_mgmd prints all configuration data to stdout, then exits.
* The output of perror --help now displays the --ndb option. (Bug #11999 (http://bugs.mysql.com/11999))
* NDB: Improved handling of the configuration variables NoOfPagesToDiskDuringRestartACC, NoOfPagesToDiskAfterRestartACC, NoOfPagesToDiskDuringRestartTUP, and NoOfPagesToDiskAfterRestartTUP should result in noticeably faster startup times for MySQL Cluster. (Bug #12149 (http://bugs.mysql.com/12149))
* Added support of where clause for queries with FROM DUAL. (Bug #11745 (http://bugs.mysql.com/11745))
* Added an optimization that avoids key access with NULL keys for the ref method when used in outer joins. (Bug #12144 (http://bugs.mysql.com/12144))
* Added new query cache test for the embedded server to the test suite, there are now specific tests for the embedded and non-embedded servers. (Bug #9508 (http://bugs.mysql.com/9508))
* Query cache is switched off if a thread (connection) has tables locked. This prevents invalid results where the locking thread inserts values between a second thread connecting and selecting from the table. (Bug #12385 (http://bugs.mysql.com/12385))

Bugs fixed:

* Slave I/O threads were considered to be in the running state when launched (rather than after successfully connecting to the master server), resulting in incorrect SHOW SLAVE STATUS output. (Bug #10780 (http://bugs.mysql.com/10780))
* On Windows, the server could crash during shutdown if both replication threads and normal client connection threads were active. (Bug #11796 (http://bugs.mysql.com/11796))
* Some subqueries of the form SELECT ... WHERE ROW(...) IN (subquery) were being handled incorrectly. (Bug #11867 (http://bugs.mysql.com/11867))
* The mysql_info() C API function could return incorrect data when executed as part of a multi-statement that included a mix of statements that do and do not return information. (Bug #11688 (http://bugs.mysql.com/11688))
* Renamed the rest() macro in my_list.h to list_rest() to avoid name clashes with user code. (Bug #12327 (http://bugs.mysql.com/12327))
* myisampack failed to delete .TMD temporary files when run with -T option. (Bug #12235 (http://bugs.mysql.com/12235))
* Concatenating USER()/DATEBASE() with a column produces invalid results. (Bug #12351 (http://bugs.mysql.com/12351))
* For PKG installs on Mac OS X, the preinstallation and postinstallation scripts were being run only for new installations and not for upgrade installations, resulting in an incomplete installation process. (Bug #11380 (http://bugs.mysql.com/11380))
* User variables were not automatically cast for comparisons, causing queries to fail if the column and connection character sets differed. Now when mixing strings with different character sets but the same coercibility, allow conversion if one character set is a superset of the other. (Bug #10892 (http://bugs.mysql.com/10892))
* Pathame values for options such as ---basedir or --datadir didn't work on Japanese Windows machines for directory names containing multibyte characters having a second byte of 0x5C ('\'). (Bug #5439 (http://bugs.mysql.com/5439))
* Mishanding of comparison for rows containg NULL values against rows produced by an IN subquery could cause a server crash. (Bug #12392 (http://bugs.mysql.com/12392))
* INSERT ... SELECT ... ON DUPLICATE KEY UPDATE could fail with an erroneous "Column 'col_name' specified twice" error. (Bug #10109 (http://bugs.mysql.com/10109))
* myisam.test failed when server compiled using --without-geometry option. (Bug #11083 (http://bugs.mysql.com/11083))
* Creation of the mysql group account failed during the RPM installation. (Bug #12348 (http://bugs.mysql.com/12348))
* FLUSH TABLES WITH READ LOCK combined with LOCK TABLE .. WRITE caused deadlock. (Bug #9459 (http://bugs.mysql.com/9459))
* GROUP_CONCAT ignores the DISTINCT modifier when used in a query joining multiple tables where one of the tables has a single row. (Bug #12095 (http://bugs.mysql.com/12095))
* UNION query with FULLTEXT could cause server crash. (Bug #11869 (http://bugs.mysql.com/11869))
* Performing DATE(LEFT(column,8)) on a DATE column produces incorrect results. (Bug #12266 (http://bugs.mysql.com/12266))
* max_connections_per_hour setting was being capped by unrelated max_user_connections setting. (Bug #9947 (http://bugs.mysql.com/9947))
* big5 strings were not being stored in FULLTEXT index. (Bug #12075 (http://bugs.mysql.com/12075))
* Updated dependency list for RPM builds to include missing dependencies such as useradd and groupadd. (Bug #12233 (http://bugs.mysql.com/12233))
* Multiplying ABS() output by a negative number would return incorrect results. (Bug #11402 (http://bugs.mysql.com/11402))
* SELECT @@local... returned @@session... in the column header. (Bug #10724 (http://bugs.mysql.com/10724))
* Character data truncated when GBK characters 0xA3A0 and 0xA1 are present. (Bug #11987 (http://bugs.mysql.com/11987))
* Comparisons like SELECT "A\\" LIKE "A\\"; fail when using SET NAMES utf8;. (Bug #11754 (http://bugs.mysql.com/11754))
* Attempting to repair a table having a fulltext index on a column containing words whose length exceeded 21 characters and where myisam_repair_threads was greater than 1 would crash the server. (Bug #11684 (
